Battle of the Epoxies: A Road to BALLS Experiment

[A5tr0 An0n]

I saw this before being edited and will comment on the part Bob took out only to avoid any future conformations with you. There was no intended hostility towards you and I am sorry things can be read in a way other than intended. It was a sincere welcome due to a thought that you might become more active here, as you are on your "native," rocketry forum. The parts about "seconds," was comment on your post about how you dislike reading the same thread on different forums which can be found here -> https://www.ausrocketry.com/forum/viewtopic.php?f=10&t=4628 and yet you commented on mine. I was just simply saying that I am glad you have changed your mind seeing as it can help the hobby and all of us grow.

So again no insults, hostility, or anything that could be interpreted as such. I do further apologize as it was taken that way.



Now to answer your other questions.

I tried the link to the source files you mentioned above but it didn't work, would you mind updating it?

Thank you for pointing out that the link is down. I do not mind at all and will put a more stable link up here shortly.

Sorry, but I am having trouble trying to work out how credible your seemingly authoritative results are - probably just me though.

I wasn't aware that I had posted any results from my own testing… do you mind sharing my own results with me?

There are 10's of thousands of epoxy systems. There a less than a dozen manufactures of the chemicals used to formulate them.

https://www.momentive.com/ is one of the big boys. Check out their product page.

https://www.momentive.com/EpoxyPhenolicComposites/ is apparently their new epoxy web page. https://www.hexion.com was another but it now takes you back to the parent company as does https://www.resins.com

These guys are where the big boys by their resins and linkers. https://www.momentive.com/ProductFamily/epoxy_intermediates.aspx?id=225 is the webpage for their resins and curatives.

Typical resins and curing agent data sheets are here. https://www.momentive.com/Products/TechnicalDataSheets.aspx?id=27567 These are the components that are blended into the epoxy systems you can buy from retail and wholesale supply houses. If you are serious about epoxies spend several hours reading these datasheet to see the differences.

They will only sell to corporations, not individuals, so don't waste you time trying to buy anything from them unless you can set up a corporate account, and they have a minimum order of several hundred dollars, but the normal quantities sold are in drums and tank cars.

Bob,

Very interesting link. These are news to me, I will check them out for possibly future builds. Thank you very much for the information.

Also there is a distributor (I would imagine more than one) that do not require minimums for all of the momentive epoxies. Some yes, but not all of them. Not all distributors carry all of the momentive line, so maybe there was a certain type that you were referring?

Here is the fixed link to the source files that I used to construct the charts. Please keep in mind that this is a zip file so make sure that you unzip it first. Also it is not entirely organized.

…and here I was thinking you were brash and cocky clearly, I’m way off…

Looks like you are in good hands, so I’ll let you get back to it.

Best of luck to you with your flight and experiment – looking forward to seeing some results.

I ran searches for all the Loctite/Henkel and Araldite Epibond that I have listed on my chart and came up with no results.

try calling. What they don't list they can get.
